IDA v4.7 and previous versions can't automatically identify the C++ or Delphi "try/finally" structures generated by Borland compilers. Some versions of Borland compilers generates try/finally structures for each function. IDA always takes these bytes not as instructions but as data. While DeDe can show them as "TRY/FINALLY". Don't know why IDA can't auto handle it.

I'm a registered user of IDA pro, but I never get permission to register in their support forum. F**K!
